SEWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 272,104, dated February13, 1683.

Application Filed May 3, 1882.' (No model.)

.To all whom tt may concern:

Be it known that I, ORVILLE R. VAN VEGH- TEN, a citizen of the UnitedStates, residing in the city ot' Brooklyn, county of Kings, and State ofNew York, have invented certain new and useful Improvements inSewingMachines, fully described and represented in thefollowingspecification and the accompanying drawings, torming a part of the same.

The present invention relates to a sewingmachine of the same generalconstruction as Patents No.

The machine shown and described in lthose patents is designed andadapted for sewing together the mouths ol' bags, or for uniting theedges of short pieces of fabric, which can readily be held between thebars of a clamping frame, such as shown in said patents. The machinethus shown is, however, for various reasons, not fitted for use inuniting the edges of long pieces of fabric, and consequently the fieldof its usefulness is comparatively limited. lt is the object ot' thepresent invention to adapt this machine for use in sewing together longpieces of material, and particularly breadths of carpeting and likeheavy fabrics, which cannot be operated upon by an ordinarysewing-machine.

To that endV the invention consists in various details of construction,both singly and in combination, as will hereinafter be fully explainedand pointed out.

In said drawings, Figure l is a plan view of a mechanism such as shownin the patents rel'erred to, but modified so as to embody the presentinvention. Fig. 2 is a transverse vertical section of the same, takenupon the line m x of Fig. l. Fig. 3 is a vertical section taken upon theline a: w of Fig. 2. Fig. 4 is a horizontal section taken on the linet/yof Fig. 2. Fig. 5 is a transverse vertical section taken upon theline z e of Fig. 1. Figs. 6 and 7 are end and side views of a gage forproperly ad' justing the edges of the material preparatory to sewingthem together.

In using the machine, niodilied as herein shown, the edges of the fabricto be united, instead of being clamped between the bars ot aclamping-frame, as in the patents referred to, are impaled upon the pinsl, which project from the edge ot' a table or counter, 2, which will beof sufficient length to receive the edges of the longest pieces offabric which it is de sired to unite. The fabric is impaled upon thepins, so that its extreme edges, in which the seam is to be taken, willproject above the edge ofthe table, the amount of such projection, andconsequenly the width of the seam, being aecurately determined by meansof a gage, 3, which is moved along from pin'to'pin, so that as thefabric is impaled its edges can be brought up snugly against thc ange 4of the gage, and thus be made uniform throughout the whole length of thepiece. The gage 3 is provided with a ring, 5, through which the operatorcan pass one of his lingers, so as .to conveniently slide the gage alongfrom pin to pin, and also hold it in place while impaling the edges of'the fabric upon the pins.

The sewing mechanism proper of the ma.- chine herein shown issubstantially the same as in the patents referred toand thereforereference is made to those patents for a specilic description of thesame. The presser-foot is, however, in the present case modified inconstruction. It consists of a single curved plate, 6, pivoted or hingedupon the end of the bar 7, projecting from the needle-bar carrier, andis provided with a spring, n8, so arranged as to press the footconstantly inward and hold the fabric snugly against the cloth-plate 9,and yet yieldsufticiently to allow any inequalities in the fabric topass and not impede the progress of the machine. The foot 6 is providedwith a slot, 10, (see Fig. 3,] to permit the oscillation ofthe needle,which is a neces sary feature in a 'machine ot' this character.

The construction of the guiding frame or way upon which the machinetravels has been changedin order to give the machine the necessary rangeof travel.

In the machine shown in the patentsreferred to the supports for theguide-bars and driv ing-rack are so arranged that the machine can onlytravel between two supports, which 'distance is sufficient for all thepurposes for which IOO prevent the movement ot' the machine, the tableoreounter 2 is provided at a suitable distance from irs edge with aseries of brackets, 13, to the top of which is fixed the rack-bar 12.The front edge of this bar is provided with a series ot' teeth whichengage with the driving-pinion14 of the sewing mechanism, (see Fig. 1,)said pinion and rack being kept in engagement b v the anti-frictionWheels 15, bearing against the opposite side ofthe rackbar, and carriedby arms 16, extending from the frame ot the sewing mechanism above therack-bar. The brackets 13 are also provided with short arms 17, theupper ends of which carry the prismatic guide-bar 11, which is nearlyembraced by the long bearing 18 on the frame of the sewing mechanism.From this it will be seen that the supports for the guide and rack barsdo notin theleast interfere with the travel ofthe machin-e. When thebearing 18 is made ot' considerable length, as shown in the present'case, it is evident that one arm and Wheel, as 15 16, will be sufcientto hold the mechanism in proper position and the wheel 14 in engagementwith the rack 12. Gonsequently, although two arms and Wheels are shown,one may be omitted Without departingV vent case the same as in PatentNo.256,518, re-

ferred to, except that in that patent the apparatus is stationary, sincethe end ot' the run of the machine is always at the same point, While inthe present case the apparatus is made adjustable, so that the run canbe terminated and the thread severed at any point desired. To accomplishthis the severing-blades 19 20 are attached to a movable carrier, 21,provided with bearings which embrace the guide-bar 11 and the front edgeof the rack-bar l2, as shown in Fig. 5. This permits the carrier to bemoved to any desired point, it being-fastened in position, when adjusted, by means of the set-screw 22, which impinges against the bar 11,and the spring-catch23, which engages with the teeth upon the rack-bar.

rlhe severing apparatus having been placed at the point where it isdesired to have the run of the machine terminate, the sewing mechanismwill bearrested at the proper time and the needle held in its Withdrawnposition, While the thread is severed by the action ot' the lever 24.-upon the projection 25 of blade 19, all as described in the patentsreferred to.

It will readily be seen that it is not essential that the needle shouldreciprocate in a horizontal plane. It may be arranged vertically equallywell, in which case the material operated upon will lie upon the top otthe table, instead of hanging from its edge.

What I claim is-- 1. The combination, with the guide and rack bars, of'the adjustable knife-carrier, substantially as described.

2. r1he combination, with the guide and rack bars, of' the adjustableknife-carrier provided with the set-screw and spring-catch for holdingit in any adjusted position, substantiallbT as described.

' 3. In a sewing-machine which moves over the material operated upon,the combination, with the cloth-plate, as 9, ofthe hinged presser-foot,as 6, consisting of a single curved plate provided with the slot, as 10,substantially as described.

4. The conibinatiomwith the brackets, as 13, provided with the guide andrack bars, as 11 12, ot' the sewing-machine frame, provided with thepartially-open bearing 18, and arms, as 16, carrying anti-frictionWheels, as 15, substantially as described.

5. The combination, with the table provided with the impaling-pins, as1, of the movable gage 3, provided with the flange 4, substantiallyasdescribed.

In testimony whereof' I have hereunto set my hand in the presence pf twosubscribing Witnesses.
